# Add a Mask to the ViDiCheck Tool

1. In this application, to better help the tool focus on the areas of interest, a Mask will be added to exclude the border of the box, along with the center dividers. Right-click within the image and select Edit Mask from the right-click menu.

2. This will launch the Edit Mask toolbar. To begin, the Width parameter will be changed from its default of 40 pixels to 50.

3. Press the Add Border button to automatically add a rectangular mask area around the border of the view.

4. In addition, the dividers in the box that separate the chocolates should also be masked. Select the Line, and while holding down the Shift key, start from the top and draw down to create a straight line to mask out the vertical divider.

5. Do the same to mask the horizontal divider.

6. Press the Apply button.

7. The Apply Mask dialog will be launched, prompting whether or not to apply the mask to all of the Views. Press Yes to continue.

8. Once the mask has been applied to all of the views, press the Close button to exit the Mask Editor.
